Specification of Letters Patent.

Patented Apr. 9. 1918.

Application filed April 28, 1917. Serial No. 165,239.

To all whom it may concern: I

Be it known that I, ELIJAH Pownns, a citizen of the United States, residing at Boonville in the county of Warrick and State of Indiana, have invented certain new and useful Improvements in-Soil-Pulver'izers, of which the following is a specification. This invention relates-to an improved earth pulverizer and the principal object of the invention is to rovide a. machine of the type described which can be drawn. across a field and which will pick up lumps of earth and carry the same to rollers between which the lumps Will pass and be ground into fine particles, one of the grinding rollers forming a support for the rear endportion of the machine and further constituting Another object of the invention is to provide an improved type of conveyer for use in connection with this machine, the conveyer being pivotally mounted at its upper end and adjustably supported at its lower end and including longitudinally extending rods having their lower end portions extended to provide gathering fingers for lifting the lumps from the ground.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the machine in side elevation.

Fig. 2 is a vertical sectional view taken along the line 2.2 of Fig. 1.

Fig. 3 is a vertical sectional view taken along the line 33 of Fig. 1.

Fig. 4 is a perspective view of one of the rods forming part of the conveyer.

The improved pulverizing machine is provided with a frame or carriage 10 provided with a forward truck 11 which truck carries the forward axle 12 upon which the front wheels 13 are mounted. The rear end portion of this frame is supported by the roller 14 which roller is positioned within the frame and is provided with an'axle 15 extending beyond one side of the frame and carries a sprocket wheel 16 for a purpose to be hereinafter described. Standards 17 are mounted upon the side bars of the frame 10 and serve not only to support the auxiliary roller 18 which cooperates with the roller 14: in pulverizing the lumps of earth but also serves to support the shaft 19 which shaft is positioned adjacent the upper ends of the standards and carries a sprocket wheel 20 about which passes a sprocket chain 21. It will thus be seen that when the roller 14 rotates, the sprocket chain which passes about the sprocket wheels16 and 20 will serve to rotate the shaft 19.

A conveyer frame is carried by this machine and is provided with side bars 22, the upper ends of which are mounted upon a shaft 23 which shaft 23 is mounted by means 7 of links 2 1 and carries a gear 25 meshing with the gear 26 of shaft 19. Therefore as the machine is drawn across the field, rotary movement will be transmitted to the shaft 23 which shaft may be termed the driving shaft of the conveyer. The lower ends of the side bars 22 are mounted upon a shaft 27 termed the driven shaft of the conveyer and journaled in the bearings 28 of the bearing yoke 29 which yoke has its bearings slidably mounted in the guide-ways 30 and is engaged intermediate its. length by the stem or adjusting screw 31. This adjusting or supporting screw 31 is passed through the bearing sleeve 32 carried by a cross bar 33 and is provided with a hand wheel 3 1 by means of which it may be rotated and the yoke thus vertically adjusted and supported in the adjusted position. As this yoke is moved vertically to the proper position, the link 24 will move upon shaft 19 to permit the conveyer frame to have the proper movement for vertical adjustment of the lower end thereof.

Rods 35 which provide slats constituting a screen bottom for the conveyer frame eX- tend longitudinally between the side bars 22 thereof and are provided with upper and lower hearings or arms 36 and 37, the upper arms 36 being mounted upon shaft 19 and the lower bearing arms upon shaft 27.

Sprocket wheels 38 are mounted upon the shafts 23 and 27 and carry sprocket chains39 which chains carry teeth 10. These sprocket chains when taken together, go to produce the endless conveyer having teeth for engaging the lumps of earth which are lifted from the ground by the forward end portions 41 of the rods 45. The forward end portions of these rods extend beyond the conveyer frame and when taken together form a scoop or rake engaging the lumps of dirt and lifting them from the ground to a position where they can be engaged by the fingers 4:0 and carried upwardly. When the lumps reach the upper'end of the conveyer frame, they pass over the upper end thereof and drop upon the auxiliary roller mating rotary 18. These lumps Will then pass between the rollers 14: and 18 and"\ \fillb"e'ground into fine particles. This groundearth willxdrop upon the ground in front of the "roller I L andtheroller Will pass over it. eonnection 'With "planting certain grain, it is eus tomary to roll the field an'ditwill thus be seen that this machine maybe used for this purpose as Well 'as for breaking up "lumps offearth.
